一、喷砂与气力输送的功能 喷砂工艺是将砂子与压缩空气形成混合气流,以大于100m/s的速度从喷砂嘴中喷出,喷击到工件表面上的砂子通过高速而密集的切削、刮削和打击作用,得以清除工件表面上的氧化皮、污垢、旧油漆及铸造型砂等残留物质。经喷砂后的工件能恢复金属其本色,适应范围小到螺丝钉大到整辆汽车均能喷砂。近年来,不少工厂对金属切削加工后解决工件去毛刺的难题,如齿轮和切管件用喷砂去毛刺的方法效果很显著。
First, the function of sandblasting and pneumatic conveying sand blasting process is to form a mixture of sand and compressed air flow to the speed of greater than 100m / s from the nozzle mouth, sprayed onto the surface of the sand through the high-speed and intensive Cutting, scraping and striking, to remove the surface of the workpiece scale, dirt, old paint and casting sand and other residual material. After blasting the workpiece can restore the metal its true colors, to adapt to a small screw to the entire vehicle can be sandblasting. In recent years, many factories solve the problem of deburring workpieces after metal cutting, such as gear and pipe cutting deburring with deburring method is very significant.
